8 Summer Foods That Can Sabotage Your Beach Body

When you order funnel cake or an ice cream sundae, you know what you're getting yourself into. But these seemingly healthy warm-weather staples might also make your jeans a little tighter if not consumed in moderation.

Frozen yogurt

Frozen yogurt

The nonfat label and 130 calories per half-cup sound almost too good to be true—and that's because they are. The posted nutrition information applies to a mere four ounces, which is far less than almost anyone eats, especially at the increasing number of self-serve chains across the country. And while it may sound counterintuitive, you're better off with a low- or full-fat flavor. "The fat is what tells your body it's eaten," says Robyn Youkilis, a nutritional consultant for Seamless. "Your body gets confused by the chemicals, your cravings start to go crazy, and you don't know what's what." To keep portion-size under control, fill your cup halfway with fruit, then put your yogurt on top. If you're itching for something sweeter, carob or dark chocolate chips and shaved coconut are among the best options.

Smoothies

Anyone's who's been to the farmers market recently is excited about the abundance of fresh, local fruit, but this produce is best consumed whole. "Normally you eat one peach or one apple," says registered holistic nutritionist Peggy Kotsopoulos. "In a smoothie, it's so easy to pack five fruits in at once." That's bound to raise your blood sugar, and if you choose the premade kind, the news gets worse. One Odwalla fruit smoothie, for example, has a whopping 44 grams of sugar—far more than the American Heart Association recommends consuming in an entire day.
